"The boys running around masquerading as sovereign entities playing soldier of fortune would wonder what to do if they finally caught the auto they're chasing."

This is an hilarious line, and I take your point. There totally are a large number of LARPers broadcasting themselves on the internet. An intelligent guerrilla does not broadcast himself on the internet.

GWOT has lasted for 20 years. There is a huge number of disaffected veterans on the street with legitimate combat skills who are no longer in active service due to stress over repeated deployments, PTSD, etc.

A lot of this is going to be on the Biden-led administration. It can try to take care of these people and address their concerns or it can choose to exclude, harass, and vilify them. I'm thinking of both the Freikorps and the Bonus Army.
